Detecting phase boundaries of quantum spin-1/2 XXZ ladder via bipartite and multipartite entanglement transitions
Sudipto Singha Roy, Himadri Shekhar Dhar, Debraj Rakshit +2
Phase transition in quantum many-body systems inevitably causes changes in certain physical properties which then serve as potential indicators of critical phenomena. Besides the t…
Monogamy of quantum correlations - a review
Himadri Shekhar Dhar, Amit Kumar Pal, Debraj Rakshit +2
Monogamy is an intrinsic feature of quantum correlations that gives rise to several interesting quantum characteristics which are not amenable to classical explanations. The monoga…
Response to defects in multi- and bipartite entanglement of isotropic quantum spin networks
Sudipto Singha Roy, Himadri Shekhar Dhar, Debraj Rakshit +2
Quantum networks are an integral component in performing efficient computation and communication tasks that are not accessible using classical systems. A key aspect in designing an…
Analytical recursive method to ascertain multisite entanglement in doped quantum spin ladders
Sudipto Singha Roy, Himadri Shekhar Dhar, Debraj Rakshit +2
We formulate an analytical recursive method to generate the wave function of doped short-range resonating valence bond (RVB) states as a tool to efficiently estimate multisite enta…
